The Birimian Greenstone Belts of West Africa
July 2013 by Chris RalphThe country we were to visit was Burkina Faso, a small country about the same size of my home state of Nevada with about 10 times more people. The second day I was in Africa, we went out to the goldfields for the first time.
Not all of these slides and debris flows will produce results, but if you search for these while prospecting in your gold producing areas, then you can increase your odds of finding new gold.
Geology is a science of general tendencies with frequent exceptions, not one of hard and fast rules that are always true and never vary. For almost every well-accepted rule of gold deposits, I can point you to a number of important exceptions.
...this county contained some of the richest placer ground found in all of California and still produces some pretty impressive finds to this day.
The other opportunity that I see is in seeking unusual types of deposits. Specifically, the prospector would be searching for the stuff no one (or almost no one) is searching for. These deposits are effectively hiding in plain view.
There are times when being able to recognize a type of rock can make you a much more successful prospector.
When prospectors and treasure hunters talk of gold in Arizona, it is the Lost Dutchman or Vulture mine they usually think of. The Lost Dutchman gold mine is just that—a myth chalked full of holes that has been embellished over time as any good legend should be.
While some future cobalt will come from recycling lithium batteries and other products, the coming huge need for cobalt is virtually a perfect storm of heavy demand and insufficient supply.
